Advances in Geomorphology and Quaternary Studies in Argentina

This book presents selected research highlights from the Seventh Argentine Geomorphology and Quaternary Studies Congress, hosted at Puerto Madryn, Northern Patagonia, Argentina by the Argentine Association of Geomorphology and Quaternary Studies (AACYG). The congress included special sessions, symposia, invited lectures and posters on the following topics: Quaternary stratigraphy and geochronology, paleontology (diatoms, mollusks, foraminifera, palynology, phytoliths, paleobotany, vertebrates), dendrochronology, climate change, paleoclimate, Pampean Quaternary paleolimnology, paleomagnetism, environmental magnetism, hydrogeochemical processes, geoarchaeology, geomorphology, structural geology and neotectonics, paleosurfaces, volcanism, geological hazards, assets, geomorphosites, and digital mapping. The Scientific Committee of the Congress has selected the papers published in this volume from more than 150 contributions in many different disciplines.
